CLAS transparent update demo

So CLAS is a project being developed actively at Arts ISIT (University of British Columbia), and also a production service used by thousands of students by multiple institutions around the world, and also a research tool. How can the CLAS service get so many upgrades every few months without affecting the students and instructors using it? You probably have heard mentions about how one or all instances of CLAS can be remote updated in seconds, completely transparently to users… So how transparent are we talking about here? Have a look!
